To all who/n, 'it mfzg/ concern.'

Be it known that I, lVILLLmiF. Llm'rnN- v scnnaciau, a citizen of theUnited States, rcv siding at Cincinnati, in, the county of llamilton andState of Ohio, have invented certain new and useful, Improvements m(lement-Applying h/lachines, of which they following is a specilication.

My invention relates to cement applying machines applicable forproviding the margin of flexible material witha narrow band of cement inthe manufacture ofl shoes, gloves, and containers of various kinds.These margins are usually skived. The margins in the course ofmanufacture of the article, are usually7 folded, and when it is theintention to fold the margin, the band of cement is usuallyapproximately twice the width of the fold` so that both the surfaceswithin the fold shall be cemented prior to folding, for the reason thatthe cement employed in this art for the purpose specified has volatileingredients and the coment adheres best to the surface of the materialatits moment of application thereto, the outer surface 'of the cementretaining its tackiness for a period of time after its ap- `The cementusually used in general work of this cha-racter has a rubber foundationor base, known in the trade as rubber cement,7

v and the, cement used in cementiug certain characters of material, forinstance, oily leather or glazed material, contains an oilabsorbingingredient such as chalk or other earthy substance, forming a thickercement, known in the' trade as. white 7 or pink cement, which, forconvenience, will hereinafter be termed thick cement. AThese cemcntsare-highly inflammable.

It is the object of my invention to provide,novel means whereby cementsofthe character stated are, readily applied in such manner as to'leave auniform and narrow band of cement on the material, and further toprovide novel means whereby cement is readily applied to' thin materialwhich contains little self-sin'iporting body without causing thematerial to crease or lap dur-ing the cement applying operation.v

My invention consists in providing feeding means for the materialarranged to feed the material in a given direction and cement-applyingmeans acting upon the material in a direction crosswise of saidfirstnamed direction; further in providing a cen'lent-applying meanscomprising a rot-ary brush and a feed-wheel within the periphery ofwhich the brush is received; further, in providing a rotarycement-applyingbrush and a` wiper or distributer in which the brush isreceived and the wall of which acts on the brush to distribute the.cement thereon; further in novel means for the material;.further innovel means for guiding the material: further, in providing a rotarycement-alnvlying brush acting to brush the cement upon the margin withamovement toward the outer edge of said the material-supports.

margin: further to provide a feeding means adapted to advance thematerial during said cement application; and, further, in vvarious partsand arrangements of parts hereinafter described. l

The invention will be further readily understood from the followingdescription and claims, and from the drawings, in which lat-ter:

vof Fig. n.

The main frame of the machine is shown' at 2l, and is" represented ascomprising a goose-neck bracket 22', which has a cementpot 23 supportedthereon in a bearing i4.

25 is a cement-feeding head, exemplified as having threaded connection26 with the shank 27 of the cement-pot for clamping the cement-pot andthe cement-feeding head in place. '.lhe shank has a cement-passage Q8therein which communicates With a cement-passage 29 in the head, theflow of cement through the latter Vpassage being contrelled by acement-valveBO for shutting oi or regnlating the flow of cement.

A cement-supplyingroll 31 ooacts with a month of the cement-feedinghead, (see Figs. l and 5), the rollbeing exemplified withcement-receiving recesses 33, the mouth heilig provided with a lip 34contacting the periphery of the cement-supplying roll for preventing thefee-'ling of excess cement, and with a lip 35 at the ifi-coming side ofsaid periphery, this latter lip being preferablyprevided with acement-return recess 36 opening outwardly, whereby excess cement isreceived and led bacleinto the cement-feeding head; The cement-supplyingroll is secured to a shaft 37, as by a set-screw the shaft beingjonrnaled in bearings 39, 40, oi" the cement-feeding head` A drive-shaft41 is journaled in bearings 42, 43, of the marin frame, and is driven bysuitable means, for instance by a drive-pnl- 'lev The drive-shaft hasdrive-connec- .tibn With the shaft 37, this drive-commotion beingexemplifiedA as aSpiral-gear 4-5 fast on the drive-shaft which mesheswith a Spiral-gear 4G fast on the shaft 37, rotating thecement-supplying roll in thc direction oi" the arrow a. (See Figs. 1, 3and 5). l

Suitable `means are provided for feedingthe. material in a givendirection, and cevment-applying means are provided havingcement-applying portions, coacting,r with the margin of the material',which, move 1n a. direction crosswise of the direction ot feedingmovement of the material.

I have exemplified the cement-applying `inea-ns enacting with the marginof the mate-l 7l on the housing 59.

mee/iis (See Figs. 1, 5, 6, and ll) The brush is capable of beingreversed on its shaft for flexing its bristles in opposite directions atdifferent times of cement application, so as to maintain said bristlesnormally radial Aon the rotary brush, whereby the life of the lbrush isincreased and its cement-applying properties enhanced.

The brush-shaft is jonrnaled in bearings 5, 57, of a housing 58, whichis clamped by means of a clamp-bearing 59 to an annular extension (l0 ofthe bearing i2. (See Figs. 2, 4land (l). A spiral-gear (3l is fast onthe drive-shaft Lill and meshes with a spiralgear (S2 fast on thebrush-shaft The gears Gl, 62 and d5,- are arranged to be received in anoil-reservoir (ifi, the wall (Si oi' 'the reservoir extendingF upwardlybetween the reservoir and the cement-siip-plying roll andcement-applying brash.

Suitable feeding` means are provided for feeding the material crosswiseoi the plane of movement. ol2 the rotary i-.ei'nent-applying brush,exemplilied as a feed-wheel (37 jonrnaled on a journal-stad (5S, shownas a shoulder-bolt clamped by means of a nut (if) in a bearing 7() oi.'a gear-covering' bracket (See Figs. l` f2, d, l, 5 and 7). Thedrive-shaft has a pinion 72 thereon which meshes with an intermediategear 73, the latter meshing with a gear ffl i'ast on the hnbof thefwd-wheel. The intermediate gear is jonrnaled on a 'journalstud75showiras a shoulder-bolt clamped b v means oia nut 76 in a bearing 77oi the brach'otl.

The rcn'xent-applying brush is arranged to rotate in the direction otthe arrow 7 andthe l'\.ed\\=ln\.el is arranged to rotate in thedirection ol' the arrow o, the peripheral speed oib the brush being-]n'eierabl.v greater, for instaure, approximately twice that oiZ theperipheral speed oi the feed-whirl, these relative speeds beinginstanced as cxan'iplcs and not as liinitations.

rlhe feed-wheel is shown oiE enp-iorm, as indicated at 7S, 'forreceivingr a. portion of' the periphery ciE the rotary brush, see Fi l,4, 5 and l0), and the `parts are preferably so arranged that theperiphery of the brush contacts the inner wall 790i the cnp-iformedi'eed-Wlncl while both the rotary brush and the feed-wheel are rotating,wl'iereby the cement received on the brush from the cemerit-V supplyingroll 1s wiped or smoothed on the periphery of the brush, 'whereby thecement is uniformly applied to the material, the

the brush .within the feed-wheel and by the inner wall of thefeed-wlieel approachr each other -toward .the cement-applying portion ofthe brush. This is accomplished prefer- 'ably by locating the aXis ofrotation of the rotary brush and the feed-wheel in different parallelplanes substantially parallel to the normal path of the, material. Therotary brush mayalso be of a diameter slightly less than the diameter ofthe truncated substantially spherical inner wall of the feed-wheel.

The feed-wheel is provided with a material-contacting rimv 81, the outeredge of which forms a preferably comparatively Sharp annular lip 82 forthe cavity -of the feed-Wheel. The bristles ofthe brush en- 'gage theinner wall.of the cavity adjacent the material-contacting portion ofsaid lipwith pressure, for causing a flexing of said bristles, asindicated at 83, (see Fig. l0), whereby cement-applying contact of thebrush with the material is made with a preferably reflexing andwipingmovement, as shown at 8.4, for applying thei 'band of cement,indicated at 85.

The materia-l during the cement-applying movement of the rotary brush isfed cross wise of the path in 'which said brush rotates, whereby thecement-brushing upon the margin of the material is accomplished in ad-irection which is the resultant `of themovements of the brushf'and thefeeding means, namely in a direction oblique to the direction of feedofthe material. (See Figs-12, 13 and 14). The margin vbeingcemente'd isdrawn lengthwise away from the bi-ush 'in a direction crosswise ofthebrush for avoiding a wiping of the cement olf of the margin lby thebrush subsequent to its being laid thefreon by the brush, a featureespecially useful in applying the thick cements hereinbefore referredto, and whereby preferably the cement is applied in alternating thickerand thinner lines, or ridges 86, arranged oliliquely across the mai-ginbeing cemented. i The manner of cement application is indi,-

` cated in Figs. l, 3, 5, 10 and 11, the narrow band of cement beingapplied to the'margin ofthe material preferably in uniform ridgef likearrangement as indicated in Figs. 12,

y 13 and 14.

lThe fold is usually made along a crease 87 extending lengthwise ofthemiddle ofthe band of cement. When the lfolded edge 88 ofthe margin islaidv upon the body-portion ofthe margin. the lines or ridges of cement'at the respective sides'of the crease extend in,- opposite directionsand crossing rela.-

tions, so that the uniformly recurrent thick portions of the cementappliedwill lap each other and cause adhesion between the folded andbody portions -of the margin when pressed together.

Experience has sh`own that whenitis desired to cement two surfacestogether, it

va set-screw 100.

in adjusted position by a jamb-nut 112 iinis desirable to provide eachof the surfaces with a facing of cement, and that the thickness of thecement-application shall be suflicient to provide a tacky facing,whereby `the two tacky surfaces will readily adhere to each other. Ihave found that in folding the margin of the material, for instance,skived margins, itN is desirable that the cement-application shallextend across the f ull widthof the faces intended to be lapped! andthat this cement-application vshall be regula-r in width, andathat theouter edges of the bands of cement shall be pronounced and suflicientlythick to provide ready adhering properties atl said outer edges, sothat, when the fold of the margin of the material is folded back uponthe body of said margin, as' indicated in Figs. 14 and 15, there shall'be a suf'licient facing 'of' cement on each of the inner faces of thefolded margin lto insure proper adherence between saidl fold and body.Laying theA cement in ridge-like arrangement increases the efficiency ofthe cement-application and insures adherence of the fold tothe body ofthe inarginforthe reason that the ridges when the fold is made arearranged in crossing relation, one upon the other, within the fold. A l

v I have shown a in aterial-supporting and guiding means coacting withthe feed-wheel and brush exemplified as follows: A primary lever 91-ispivotcd on trunnionfscrews 92. (See Figs. 1, 3, 4,' 5, (l and 10). Amaterial-supporting wheel 93 is journaled on a journal 94 of a, stud 95,the feed-wheel being rotatively held between an annular shoulder 96 ofsaid stud and a retaining screw 97. The stud has a stein 98 clamped in abearing 99 of the lever 91 by means of '.lhc trunnion-screws 92- arethreaded in bearings 101 and secured in .and is mounted'in the socket107 of an ad- ]ii. ;ti'ng screw 109 adjustable in a threaded vbearing109 of the lever 91 for determining the readiness of yield of the wheel93.,V Ai set-screw 111, threaded in the-lever and held pingeslthe shelf103l for adjusting the ap proach between the,- wheel 93 and thefeedwheel G7. l

An auxiliary lever is pivoted at 11G to the primary lever and has on ita support 117 upon which the margin of the material arranged to besupplied with the band ofcement is supported. The. support is normallyurged upwardly by a,s]' ring 121 rejustable in a threaded bearing A12stof the primary lever. The upward liinit of the support with relation tothe primary lever -12t-` ceived'in a socket 122 of ,the auxiliary leveri and-in the socket' of a socket-screw 123 adi contact ol the. brushwith the lower feedis controlled by an adjusting screw 126 adjustable inan arm 1*.7 ot' thel auxiliary lever and arranged to contact.a lug 128on the.

'.primary lever and locked in adjusted posiable. in a depending lug.1?2v depending .tron1 the. housing Titi and held in adjusted positionsby a leek-nutI 132i. the setserew being arranged to strike. the headol'y a bolt 191i threaded into the auxiliary lever. The iorward oriii-'feeding side ot'the support .117.

is rounded. .is shown at 135. (seey Figs. it, (3, h. .l and ll l. toeon'lorln substantially to the rounding oi the wheel EW), the'support. pret erahly terminating at. its rear edge 12313 adjaeent the l'orwardtare otl said brush, so that when the imiehine is ruiming withoutmaterial passing therethrough a minimum sur't'aee ol'` the support ispresented to the, brush. this surl'aee heing merely an edge surtarewhieh would in turn be wiped elean by the edge o'le the material ledtherethrough, so that. delaeing ot the 'liaee .side oi' the. material isavoided. it being understood that the taee side ol the material whenbeing ted through tlie'm'aehine herein, exemplitied is presented towardthe lower roll and the. support. 'lhis arrangement o'l" parts has thefurthe-'n advantage that the material is urged toward theeement.apply'ing brush with greater loree at the. points ot initial.eontaet o'l the brush with the. margin ot the material. which in thepresent exemplilieation would he at points above the suppllting-wheel.)I at. the side and -above the rear edge 12%(3 ot the support 11i' atthe. trout, whereby a hollow 1337 see Figs. 10 and 11), is formed underthe out-feeding vand outer edge. portions ot the margin ot the materialunder the. brush, tor permitting` -yield ot the margin heilig eeinentedwhich increases toward said ont'leeding and outer edge portions, whichvield, while it. is not sulilcient to prevent cement-applieation uponsaid margin. portions, aids in preventing a. -wiping away ot the cementpreviously applied, which is especially use'lul in cement-appli.- eationto oily and glazed surfaces.

In. order to aid in cleanliness ot' work, the lower feed-roll is ott-settrom the. upper feed-roll' so as to leave ay space 141, (see Figs. 1, 3,5 and 10), indicating the ott-set relation between the two wheels,whereby7 wheel is avoided.

y improved deviee'turtlier enables the. width ot the band ot'cement-ajiplication to be adjusted by merely adjustingthe gage. aga instwhich the Vedge ot the material .is received,

.so that cement-applications ot ditlereut widths may be applied at themargin ot the 14.9 between cement-supplyin,1

material. The. support is provided with a rearwardly upwardly inclinedsupporting tace, as shown at 1112, so that the. tapering -edgeiot thesl"ved material, which becomes .ot the periphery ot the rotarycement-applying brush and the. support below, in which the tapering edgeor' the. material is received, t'or causing uniformity olf cement-apphca'ti on.

'.`he gage. shown at 1li, has a rounded trout end 11?) and a laterallyextending tongue liti, (see Figs. (i, S and 9), the latter having itslower tace rounded, as shown at 117, to contorni to the. rounding ot theforward edge o'l' the uiaterial-support, so that the. tongue may be,adjusted lengthwise of this rounded edge and be in close relationtherewith. hold-down tinger 14S coaets with the gage and is arranged tohold down the edge o'l the imiterial, forming a channel it and the!inateri:il-supportI through which the edge ot the material is guided.The. gage is provided with a slot 150, and the hold-down finger with aslot 151, a screw 15;) passing through said slots and threaded into theauxiliary lever 'for securing the. gage and the hold-down linger inadjusted positions. rl`he adjustments of the parts permits the gag to beretracted for a greater width ot margin being cemented, while. theylinger may be `adjusted 'torwardly tor extending overa greater portionot the margin beingeemented, or other rela.- tive adjustments ot the.parts may be. had.

ln order to provide further cleanliness ot operation 1- provide acement-directing shelt` 155 arranged to receive any droppings of cementtrom the iirteeding portion of the head, for instance when the. machineis being run idle, and directing the same to the brush for being carriedto the upwardly moving face of the brush toard the cement-supplying rolland back into the head. I have shown this shelf as projecting from thehousing 58 and provided with a cement-directing groove 15G.

'l have exemplified the axis of rotation 0f the cement-applying brush asextending at right angles to the axis .of rotation of the feed-wheel,but l do'not desire to be limited to such relations of parts.

A gear-cover 157 may be provided above the' gears for thece1ncnt-supplyingroll.

A- linger guard 158 is secured to the cement-feeding" head, as-by screws159, and

has a lower curved end 160 received in front of and under the feed-rollfor guarding against contact of the finger of the operator 'with thefeed-roll.

Cement of the character herein mentioned has a tendency to string duringapplication. In order to avoid the detrimental effects of thisstringingl provide a rotary part in rear ofthe brush. finger 161 isjournaled in a bearing 162 and has a gear 163 fast thereon which isineshed by a gear 164 fast on lthe drive-shaft. The linger preferably`acts in close proximity to the rear face of the brushv and continuouslyrotates for wrapping upon it the strings of cement and transferring thesame back upon the brush. It further acts to press upon the rear face ofthe brush if the brush is spread by excess cement therein, whereby theexcess cement is pressed out of thebrush and trans- .ferred back intothecement-head through i the return-recess 36. The rotary finger fur-Ither preferably extends into the cavity of the cup-like feed-wheel,thereby wrapping upon itself any strings formed at the edge of thecavity of the feed-wheel and wiping the same back upon the brush.
